Each stream has different processing time targets, backlogs, etc.
Personally I always focused on FSW as this is the stream I applied for.
When it comes to FSW-O, there are still old, pre-covid applications stuck in the system but there are relatively few of them. New applications are being processed very fast but of course things can always change. Plus then you have to wait for COPR which can sometimes add another couple of months.
It's best to plan for 6-12 months of processing time but there's high probability that it maybe under 6 months.
